Comparison of urinary albumin excretion between Maoris, Pacific Island Polynesians and Europeans with non-insulin-dependent diabetes.
Elevated urinary albumin excretion is a marker for increased mortality and morbidity in European subjects with non-insulin-dependent diabetes. Urinary albumin excretion was compared in 32 Maoris, 34 Pacific Island Polynesians and 66 subjects of European origin with non-insulin-dependent diabetes attending a diabetes clinic in Wellington, New Zealand. The random urinary albumin to creatinine ratio was used as an estimation of urinary albumin excretion rate. The random urinary albumin to creatinine ratio was significantly higher in Maori and Pacific Island Polynesian subjects, compared to diabetic Europeans (geometric mean urinary albumin to creatinine ratios were 13.13, 12.00 and 2.79 mg/mmol respectively, P less than 0.05). These findings would be consistent with the high mortality and morbidity seen in the Maori and Pacific Island Polynesian diabetic populations. The correlation between hypertension and increased urinary albumin excretion was stronger in the Europeans than in the Maoris and Pacific Island Polynesians studied, suggesting that differences in blood pressure alone are unlikely to account for the observed differences in albumin excretion. Follow-up studies are required to determine whether diabetic Maoris and Pacific Island Polynesians with increased urinary albumin excretion have a similar prognosis to their European counterparts.
